Narrow Artificial Intelligence
Description
Narrow AI, or Weak AI, refers to Artificial Intelligence systems that are designed and trained for a specific task or a narrow set of tasks. These systems cannot operate beyond their programmed capabilities, but they can perform their designated jobs with remarkable efficiency—sometimes even better than humans. Unlike General AI, Narrow AI does not possess consciousness, understanding, or general reasoning ability. It's the most common type of AI we interact with today.
Examples (Code)
Below is a simple example of a Narrow AI application using a DecisionTreeClassifier to classify flowers using the famous Iris dataset:
from sklearn.datasets import load_iris
from sklearn.tree import DecisionTreeClassifier
from sklearn.model_selection import train_test_split
from sklearn.metrics import accuracy_score
# Load data
iris = load_iris()
X = iris.data
y = iris.target
# Split dataset
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)
# Train Decision Tree (Narrow AI for classification task)
clf = DecisionTreeClassifier()
clf.fit(X_train, y_train)
# Predict and evaluate
y_pred = clf.predict(X_test)
print("Accuracy:", accuracy_score(y_test, y_pred))

Interview Questions with Answers
What is Narrow AI?
Narrow AI refers to AI systems designed for a specific task such as image classification, speech recognition, or playing chess. It does not possess general reasoning capabilities.
Is Narrow AI the same as Weak AI?
Yes. Narrow AI is often referred to as Weak AI because it doesn’t have self-awareness or general intelligence.
Give some examples of Narrow AI.
Examples include spam filters, chatbots, recommendation systems, and facial recognition software.
How does Narrow AI differ from General AI?
Narrow AI is task-specific and cannot perform beyond its scope, whereas General AI can theoretically perform any cognitive task a human can.
Is ChatGPT an example of Narrow AI?
Yes, ChatGPT is a Narrow AI model designed for understanding and generating human-like text based on its training data.
